filter media

[finfan]

i was wondering what most people use as their filter media, after going through various phases over the years, i have finally decided that good old sponge is the best filter media (for me at least), so for my tanks i only use sponge (for both canister and hob) - basically fill out all the space within the filter with sponge, no carbon, no ceramic chips, nothing else and it works just fine for me

what do you use?

I use this blue and white stuff that you can get from the air filter places.

It depends on the filter; in my canisters I use the rings and substrat that came with the Eheim 2117 kits, with sponges on the intakes. In my HOBs I use AC sponges in all of them.
